Cambridge Secondary (7-9). Stage 7. MCE Science. Workbook - Unit 1: Introducing Science - Question 15

Skills are the things that we do in order to practise science. Making observations is one of the skills. We make observations using our senses or instruments. Draw a line to match each observation with the sense or instrument used to observe it.

| Observation | Sense or instrument used |
|---|---|
| change in colour of a chemical reaction | ears (hearing) |
| cluster of stars | eyes (sight) |
| flavour of tea | metre rule |
| length of a plant’s stem | microscope |
| mass of a bag of fruit | nose (smell) |
| smell of fresh cut grass | scale or balance |
| sound of a bird call | stopwatch |
| temperature of a baby with fever | taste (tongue) |
| inside structure of a leaf | telescope |
| time taken for a racing car to reach the finish line | thermometer |
